System for transporting items on vehicles

Abstract

A roof rack system includes structures for connecting item holders to crossbars which simplify the attachment the item holders. The structures include slots in the crossbars and extensions on the items holders to mate with the slots. One of the crossbars includes a locking mechanism for locking the item holders into the crossbar. The locking mechanism includes a rod within the crossbar which mates with the extension on the item holder to retain the extension within the crossbar.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of provisional patent application Ser. No. 61 / 281,877 filed Nov. 23, 2009.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to rack systems for attaching items to the roof of a vehicle for transportation. More particularly, the invention relates to a system for easily attaching item supports to crossbars on a vehicle rack.[0004]2. Discussion of Related Art[0005]There are many designs for racks to attach items to the roof of a vehicle for transport. Many carrier racks are designed for mounting to the roof of vehicles such as automobiles to transport cargo, recreational equipment and the like. However, such racks have have many disadvantages.[0006]Racks available today have static crossbars, typically in the form of a square or round steel tube or an ovalized aluminum extrusion. The mechanisms for affixing attachments (e.g. bike carriers, ski carriers, cargo boxe...

AI Technical Summary

Benefits of technology

[0017]According to another aspect of the invention, the extensions are symmetrical to facilitate simple and rapid front-to-back or back-to-front reversal of attachments.

[0018]According to another aspect of the invention, a bracket can be attached to a wall. The bracket mates with the extensions on the attachments. This allows for seamless and rapid storage of either attachments (e.g. boxes or basket) or attachments along with affixed relevant equipment (e.g. bike attachment with affixed bicycle).

[0019]Since the crossbar and attachments have a consistent arrangement, attachments are easily interchangeable between vehicles having the system installed. Because attachments can fit rapidly onto the system on every vehicle where it is installed, attachments can be easily and quickly moved from vehicle to vehicle. Additionally, the system has a reduced cost / investment because attachments can be transferred quickly and easily from vehicle to vehicle thereby requiring users only one attachment for each item (such as a bicycle holder).

[0020]The attachments can be easily removed from the vehicle when not in use. This leads to reduced windage on vehicles, better gas mileage, the resulting cost savings and a lower CO2 footprint, which aids the reduction in greenhouse gas emissions. It also reduces wear-and-tear on attachments because they don't have to be out in the elements (sun and weather) all the time; only when they are being used. When they are not in use, attachments and / or their related equipment are conveniently stored out of the elements.

Problems solved by technology

The height of such roof-top boxes makes it impossible for some vehicles to fit through garage door openings or into parking ramps with the roof-top box in place.
